PERIOD COVERED:  0000Z (UTC) 04/29/96 - 0000Z (UTC) 04/30/96

Daily Status Report as of 121/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed WF/PC-2 6708 (Multiwavelength Imaging of Two Luminous =
Blue Compact Galaxies)

       The WF/PC-2 was used to make multiwavelength (i.e., five different =
wavelengths) images of the luminous blue compact galaxy ESO338-IG0.  The =
images will be used to study star formation and dust distribution in this =
young galaxy.  The observations were executed as scheduled, and no =
anomalies were noted.

   1.2 Completed Two Sets of GHRS/2 6172 (CRIMP2: Cycle 5 =
Condensed-Regimen Integrated Monitoring Program)

       The High Resolution Spectrograph (Side Two) was used  to obtain =
darks, internal flats (in photoscan mode), wavelength calibrations and =
observations of standard star BD+28D4211.  This includes detector =
calibration, sensitivity monitoring, and wavelength monitoring.  The obser=
vations were executed as scheduled, and no anomalies were noted. 

   1.3 Completed WF/PC-2 6235 (High Resolution Imaging of Radio Galaxies =
at Redshift Z~1.0)

        The WF/PC-2 was used to make observations of faint radio galaxy =
3C241 which is known to have a redshift of about one.  This is to attempt =
to determine the cause of the alignment of the blue-excess along the =
radio axis.  The observations were executed as scheduled, and no =
anomalies were noted.

   1.4 Completed WF/PC-2 6187 (WF/PC-2 Cycle 5 Calibration: Earth Flat)

       The WF/PC-2 was used to make Earth streak flat calibration images. =
 These streak flats will be used to produce flat fields, to map the OTA =
illumination pattern and, in combination with other data, to produce new =
superflats.  The observations were completed as planned, and no problems =
were reported.

   1.5 Completed WF/PC-2 5996 (The Morphology of Field Galaxies at High =
Redshifts)

       The WF/PC-2 was used to make observations  of several field =
galaxies (Field-1000) in order to study their morphologies.  The =
observations were completed as planned, and no anomalies were reported.

   1.6 Completed WF/PC-2 5972 (Determination of the Extragalactic =
Distance Scale)

       The WF/PC-2 was used to make observations of the galaxy NGC-4725 =
looking for standard candle Cepheid variable stars.  The purpose of these =
observations is to help estimate the Hubble constant with an accuracy of =
10%. T he observations were executed as scheduled, and no anomalies were =
noted.

   1.7 Completed WF/PC-2 5997 (The Cores of Elliptical Galaxies in the =
Coma Cluster)

       The WF/PC-2 was used to make observations of the large elliptical =
galaxy IC3959 which is located in the Coma Cluster.  The purpose is to =
study the luminosity profiles in the central nuclear region.  The =
observations were completed as scheduled, and no anomalies were noted.

   1.8 Completed WF/PC-2 5913 (Low-Mass Binaries and Luminosity Fuction)

       The WF/PC-2 was used to make observations of the low-mass binary =
system NGP011 (Late Type Class M dwarf stars).  The intent is to =
determine why the local stellar luminosity function is flat below =
Mv=3D12, while that found from more distant stars falls by an order of =
magnitude by Mv=3D14.  The observations were executed as scheduled, and no=
 anomalies were noted.

   1.9 Completed WF/PC-2 6365 (A Snapshot Survey For Companions and =
Clusters around Wolf-Rayet Stars)

       The WF/PC-2 was used to make snapshot observations of Wolf-Rayet =
star WR56 in order to look for companion stars and clusters.  Photometry =
was performed on the Wolf-Rayet stars and associated stars.  As reported =
in 2.1, the FGS acquisition for this proposal failed.  No further =
anomalies were reported.

2.0 FLIGHT OPERATIONS SUMMARY:

   2.1 Guide Star Acquisitions: 

                            Scheduled Acquisitions : 7
                                        Successful : 6

       As documented in HSTAR 5588, the single axis FGS primary =
acquisition at 120/234254Z failed.

                          Scheduled Reacquisitions : 4
                                        Successful : 4

   2.2 FHST Updates: 

                              Scheduled : 10
                             Successful : 10

   2.3 Operations Notes: 

       There were no operational problems.

3.0 SIGNIFICANT FORTHCOMING EVENTS: 

        GSFC Internal Simulation #4 (EVA #2) will be conducted on =
Thursday.
